Measurements and Analysis in Power System Harmonics

The concepts of measurements and analysis in power system harmonics are discussed in this elaborative book. The rise in the usage of power electronics equipment has led to significant distortions. An ideal AC power system is purely a sinusoidal wave both voltage and current. However the increasing existence of non-linear loads changes the aspects of voltage and current from the perfect sinusoidal wave. This alteration from the perfect wave is reflected by the harmonics and although its effects vary based upon the type of load it affects the effectiveness of an electrical system and can create extensive damage to the system and infrastructure. Establishing ideal power quality after a good design and devices leads to productivity efficiency competitiveness and profitability. However nobody can promise the ideal power quality when there is a good design if the accurate tests and working methods from the collected information are not properly assured at every moment; this entails processing the actual information accurately. This book discusses harmonics analysis ranging from the actual measurement data to the study of various industrial environments and electronic tools.
